Restructure app design

[space-ravi]

Need to have a conversation with 18Logic about the entire app. Some thoughts:

• Currently, many of the screens look the same, but require separate image files for home and arrow buttons
• We really only have a small number of standard screens, can we take advantage of this?
• App is going through a UI redesign. Would be great if there was a simple way to quickly change color of all header bars, all fonts, etc.
• Some screens take a long time to load. We need to increase efficiency of this.
• Logic ability has slowed down app even more
• Takes a long time to download data from the server (upon initial download on the login screen, and after pressing download button)
